Been there - done that. Does not work! It has something to do with microsoft's passwordless accounts. I finally - after trying everything I've read everywhere used my PHONE number for user name and skipped the password and it actually connected!
Go figure!
Thanks for your tip CAH17. I don't yet understand it, but entering my phone number (without country code) and Microsoft Account password allowed to connect to my other laptop to see the shared folders. Weird to me that it doesn't work with my Microsoft Account email address. I didn't try skipping the password like you did. Remote Desktop login still isn't working, but I don't need that right now.
Just to be clear about my situation - I'm trying to connect from my Windows 11 laptop to my Windows 10 laptop at home.
